16 essentials for CNC milling

In the actual production of milling processing, including CNC machining tool setting, workpiece clamping, tool selection and other application skills, today I briefly summarized the main points of milling processing for everyone, it is worth seeing!

1. Power capacity

Check the power capacity and machine rigidity to ensure that the machine tool can use the required milling cutter diameter.

2. Workpiece stability

Workpiece clamping conditions and considerations.

3. Overhang

Make the tool overhang on the spindle as short as possible during processing.

4. Choose the right milling cutter pitch

Use the correct tooth pitch of the milling cutter suitable for the process to ensure that there are not too many blades involved in the laser cutting china, otherwise it will cause vibration.

5. Cutter

For narrow workpieces or when milling with gaps, ensure that there are enough blades to take the knife.

6. Blade geometry selection

Use positive rake angle indexable inserts as much as possible to ensure smooth cutting action and lowest power consumption.

7. Use the correct feed

By using the recommended maximum chip thickness, ensure the correct feed of the insert used to achieve the correct cutting action.

8. Cutting direction

Use down milling as much as possible.

9. Part considerations

Workpiece material and configuration, as well as the quality requirements of the surface to be processed.

10. Blade material selection

Select the geometry and material according to the type of  medical machining and the type of application.

11. Damping milling cutter

For longer overhangs that are more than 4 times the tool diameter, the vibration tendency becomes more obvious, and the use of vibration-damping tools can significantly increase productivity.

12. Entering angle

Choose the most suitable entering angle.

13. Milling cutter diameter

Choose the correct diameter according to the width of the workpiece.

14. Milling cutter position

Position the cnc milling china correctly.

15. Milling cutter cut in and cut out

It can be seen that through arc cutting, the chip thickness when retracting is always zero, so that higher feed and longer tool life can be achieved.

16. Coolant

Use coolant only when deemed necessary. Generally, milling can be performed better when no coolant is used.
